spring boot默认的日志是logback.
logback.xml如下：
代码语言：javascript复制<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="30 seconds">
<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%-4relative [%thread] %-5level %logger{35} - %msg %n</pattern>
</encoder>
</appender>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<!-- encoder 默认配置为PatternLayoutEncoder -->
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
</pattern>
</encoder>
</appender>
<appender name="logFile"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${catalina.base}/logs/e-service.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>${catalina.base}/logs/e-service.%d{yyyy-MM-dd}.zip</fileNamePattern>
<maxHistory>30</maxHistory>
</rollingPolicy>
<layout class="ch.qos.logback.classic.PatternLayout">
<Pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{40} - %msg%n</Pattern>
</layout>
</appender>
<!-- <logger name="com.hengbao.fundcheck.repository" level="DEBUG"/> -->
<!-- 以下这一句至关重要如果没有，就无法输出 sql 语句 -->
<!--注意：在 spring boot 中，想在控制台打印 mybatis 的 sql 语句，只需要配置下边这一句就好了。-->
<!--如果想要记录更详细的 SQL 日志，只需要把下面的日志级别改成 TRACE 就可以了-->
<!--即将 mapper 接口打入 logger 就行。-->
<logger name="com.kaigejava.project.mapper" level="DEBUG"/>
<logger name="org.mybatis.spring" level="DEBUG" />
<logger name="org.apache.ibatis" level="DEBUG" />
<logger name="java.sql.PreparedStatement" level="DEBUG" />
<logger name="java.sql.Statement" level="DEBUG" />
<logger name="java.sql.Connection" level="DEBUG" />
<logger name="java.sql.ResultSet" level="DEBUG" />
<logger name="com.alibaba" level="INFO" />
<logger name="org.apache.commons" level="INFO" />
<logger name="org.apache.zookeeper" level="INFO" />
<logger name="org.springframework" level="INFO" />
<logger name="org.quartz" level="INFO" />
<root level="INFO">
<appender-ref ref="console" />
<appender-ref ref="logFile" />
<appender-ref ref="STDOUT" />
</root>
</configuration>说明：
<logger name="com.kaigejava.project.mapper" level="DEBUG"/>
这句很重要的。
